Hi , I am trying to build a cloud web application which can do below tasks-: Create Azure IOT Edge Devices on IOT Hub using IOT Hub SDK. Create Standard and Layered Deployment for the target devices using IOT Hub SDK. I was able to accomplish the first task using the RegistryManager API in IOT hub SDK. But I am not able to find any sample SDK or API via which I can write code (in JAVA) to create deployments for IOT Edge Devices. Can you please help me out here if, is there any SDK or API available to accomplish my second task? I do checked the documents suggesting to do the same thing via Azure CLI, Azure Portal and Visual Studio Code. Deploy and monitor IoT Edge modules at scale using Azure Portal using below link. https://learn.microsoft.com/en-us/azure/iot-edge/how-to-deploy-at-scale?view=iotedge-2020-11 I want to accomplish the same thing using any SDK or API provided. Please let me know if the same is available. Thanks In Advance! Regards Shashank

Hello @Shashank Kaushik , this is a good question! I have worked with the Azure IoT Hub Rest API which you want to use for this. Microsoft does not provide a higher level API (written in C#, Java, etc.) at this moment. You probably want to use this Create or Update Configuration API. Please verify this is working on both 'direct internet connected IoT devices' and Edge devices.

Thanks @Sander van de Velde | MVP . I was able to check some example of the API use cases like that. I think i will be able to use these API's to make some custom web app solution for cloud.

Hi @Sander van de Velde | MVP

Are you sure that this is not possible using the SDK?

As far as I understood, this can be accomplished with the RegistryManager using the AddConfiguration method. I am not sure about Java though.

I also read your blog post about this (this one), but I am a bit confused now.

Hello @Andreas F,

thanks for visiting my blog :-)

The blog post is about creating a single deployment manifest.

The question above (from 3 years ago) is about layered deployments.

Layered deployments is a mechanism to let the IoT Hub compose a deployment manifest based on feature tags.

I am not sure if the SDK has changed in the past years but I expect nothing has changed..

Hi Sander

Thank you for coming back to me despite this thread being old.

For individual deployments you are right, I think REST is the only way.
For automatic and layered deployments, OP could use the part of the SDK that I linked in my previous reply.

Greetings
Andreas

Ah, yes. I have to read better :-)

It seems it made it to the SDK in the end.

This is good news, have to try the SDK version for myself now :-)
